The MATCO-NORCA b-l4505 is a 1-inch brass 45-degree elbow fitting designed for directional changes in plumbing and piping systems. This fitting redirects flow at a 45-degree angle, making it suitable for installations where a gradual change in pipe direction is needed. Brass construction provides corrosion resistance and durability in both hot and cold water applications. Licensed plumbers and pipefitters install this type of fitting in residential and light commercial systems during rough-in and retrofit work.
This elbow is used in residential and commercial plumbing systems where a 45-degree directional change is required. Typical applications include supply lines, hydronic heating loops, and general water distribution piping. The 1-inch size fits standard piping found in both new construction and remodel projects across a range of building types.
Designed as an OEM-style replacement or new-installation fitting for standard 1-inch brass threaded plumbing systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before removing or installing any fittings. Use appropriate thread sealant or PTFE tape on threaded connections and tighten to the fitting manufacturer's standard for brass fittings. Do not over-tighten, as brass threads can be damaged by excessive force.
